15 lbs PuriTech Stabilizer Conditioner Cyanuric Acid UV Protection for Swimming Pools and Spas

Best price/pound for CYA that I have found. Shipping was very fast, exactly as pictured. It is just a zip-tied bag inside the box. Don't need more frills, just get my chemicals to me and these guys deliver. Add the CYA to a sock or pantyhose inside your skimmer basket so you don't blast a bunch of small pebbles into your pool pump impeller. Takes a few days to dissolve.I follow the protocol set by Troublefreepool.com to set and maintain my pool chemicals. CYA is a critical component to not only keeping your chlorine levels stable but also to not destroy your wallet when the sun eats up all your un-stabilized chlorine. You can figure to use about 1 lb of CYA granules to raise 10,000 gallons of water by 10ppm. It is always better to undershoot a bit, wait a few days for full saturation and then test your CYA levels at any pool store or using a home kit (I use the Taylor K-2006 test kit). Once you hit your target you don't need to test it again until the start of the next season. You can always add more CYA but you cannot lower it unless you drain some or all your pool and refill with fresh water or have some kind of psycho reverse osmosis filter on your pool. Also be very careful if you use dichlor shock or stabilized tablets since those contain a small amount of CYA. Remember it doesn't really go away, just continues to concentrate. This is not a problem if you use liquid chlorinator (bleach). My father used so much pool shock (dichlor) to attack a algae problem that he essentially stabilized 100% of the chlorine he was adding to the pool so none was able to actually oxidize the crap building up in his system. I asked him about his CYA levels and he didn't even know what that was, only that shock wasn't helping. Take a test bottle to your local pool store and they should be able to test for this for free.

Packaged great and price is good too.

works just as good as the stabilizer from the pool store, only it doesn't cost as much as the pool store!!!

It’s a pool chemical. I am not a chemist but it seems to be working perfectly.

I had never used this acid before and was surprised at how slow it was to dissolve. I was very cautious about adding too much so I added it slowly over a couple of weeks and kept checking on the level. Good value for the price.

This product is the same as you would buy at Walmart, Home Depot or any pool store, but for much much less, $20 for a 5 pound bottle versus the cost of this is a no brainer, just add the proper amount needed to your pool skimmer basket as the manufacturer suggest, not sure why you would want to use a nylon sock as some do, just that much more of a hassle and not necessary, Have been adding this product directly to my pool skimmer basket for over 28 years, the product dissolves nicely and enters the pool system without any issues, if you want to save a bunch of money this is the only way to go with a quality Chlorine stabilizer product to your pool water.

Great price per lbs.

This gets my CH right where it needs to be in my pool.
